MEDFORD, Ore. – A Southern Oregon man who hoped to delay a three-year burglary sentence by destroying the records of his case has been sent to prison for 15 years for trying to blow up the prosecutor's office.

The Medford Mail Tribune reports (http://bit.ly/1tb1eHI) 47-year-old Alan Leroy McVay apologized in federal court Monday for hurling a bomb at the offices of the Jackson County district attorney before dawn on Nov. 13.

He was due in court the next day for sentencing on a plea bargain over burglary and theft charges.

His plot to put off sentencing fizzled. A pipe bomb failed to detonate the 7-gallon propane tank it was taped to.

McVay pleaded guilty in May to a charge of malicious destruction of property by explosion.
